Move over, millennial pink — it’s about lilac now. All year, lilac has been the “it” color of choice for Hollywood celebrities and real-life royals. Most recently, Julia Roberts stepped out on the red carpet in a lilac suit by Givenchy , the same label behind Meghan Markle ’s wedding dress. Roberts matched with her longtime Hollywood stylist, Elizabeth Stewart. Earlier in October, Kate Middleton was spotted wearing a lilac wool crepe A-line dress by Emilia Wickstead . Similar to Roberts, Naomi Watts sported a menswear-style lilac suit at the 2018 Hugo Boss Prize event in New York. And earlier this spring, Victoria Beckham wore a lilac suit while spending time in her hometown of London. Lilac is the perfect shade between pink and purple. In 2017, the color craze was millennial pink. This year, Pantone designated the 2018 color of the year as “ultra violet.” Lilac, however, is defined as a “pale pinkish-violet color,” which is nestled perfectly in between both shades. The Guardian described lilac best as a “mature pink.” Pink is often reminiscent of a girl’s youth and childhood, whereas lilac is the color of her adulthood. This is especially visible in Vanity Fair ‘s July 2003 cover story, “Raining Teens,” which featured the top young Hollywood talent of the time across film and television. These young teen royals included Hilary Duff , Mary-Kate and Ashley Olsen , Lindsay Lohan , Alexis Bledel , Amanda Bynes , Mandy Moore , Raven-Symoné, and Evan Rachel Wood. At the top of their careers, the stars — whose ages ranged from 16 to 17 years old — each wore pink for the cover in front of a blush-pink backdrop. In 2018, lilac is a color synonymous with maturity, worn by sophisticated women including Amal Clooney, who wore a lilac Atelier Versace gown to the 74th Venice Film Festival. The color sits nicely in the pastel family among baby blues, mints, and periwinkle. It still looks fresh, but not childish. Plus, fashion labels Rodarte and Salvatore Ferragamo included lilac gowns and blouses in their Spring 2019 collections, signifying that this trend is far from over. Keep in mind, when you’re shopping for lilac apparel, look for items with clean lines and simple silhouettes. It will allow the color to truly shine.

For Princess Eugenie ’s royal wedding at Windsor Castle on Friday, fall fashion was in full bloom. The royal family attended wearing stunning monochromatic looks in rich jewel tones like ruby, sapphire, and emerald. Kate Middleton glowed in a deep raspberry A-line dress by Alexander McQueen with a matching ruby fascinator. The Duchess of Sussex, Meghan Markle , was all smiles with Prince Harry, whom she married at the same altar just five months ago. For this occasion, she opted to wear a modest midnight blue coat and dress by Givenchy , the same label behind her wedding dress. Princess Eugenie’s sister, Princess Beatrice , wore blue as well — a two-piece sapphire-colored set by Ralph & Russo — the designer duo behind Markle’s engagement dress . Beatrice, who is typically known to wear extravagant fascinators , decided to wear a more minimalistic deep purple headband on the special day. The simple accessory complemented her classic, tailored look. The mother of the bride, Sarah Ferguson , aka Fergie, wore a gorgeous silk emerald wrap dress that featured a small train by her go-to designer, Emma Louise. She designed the dress Fergie wore at Meghan and Harry’s wedding too. Pippa Middleton , who is reportedly days away from giving birth , shined in her chic maternity look, wearing a long-sleeved emerald dress by Emilia Wickstead . From ruby red to sapphire blue to emerald green, the fall season’s color palette is crystal clear: It’s all about jewel tones. Picture yourself wearing a lavish ruby-colored A-line dress for Thanksgiving, an elegant emerald dress like Pippa’s or Fergie’s for Christmas, or a blue sapphire dress at your next office holiday cocktail party.
